1. Who are you and what do you do?
“I’m Manuel Persa, a contemporary artisan and director of the ARBIO studio, based in the Redes Natural Park (Asturias). From my lab-workshop, I design and create unique pieces using my own material, Biocastanar®, derived from chestnut shells and natural binders. I specialize in ephemeral architecture, window displays, furniture, lighting, and sculptural objects, blending digital design, 3D printing, and traditional craft techniques. I also share my experience through biomaterials and sustainability workshops for students and professionals.”
2. Why did you choose this profession?
“Since I was a child, I’ve loved drawing and building; I grew up in a home without an artistic background, although my grandfather was a carpenter, and touching his tools sparked my curiosity. Over time, my training in design and my move to the natural environment of Redes led me to combine creativity, nature, and innovation. What I’m most passionate about is transforming agricultural waste into functional and sustainable art.”
3. Who are your main clients?
“Most of my clients are galleries, contemporary art collectors, interior design studios, and architects who value exclusive pieces with environmental values. I also work with public and private organizations in specialized training, offering workshops to emerging designers, makers, and students interested in biomaterials.”
4. What materials do you use and where do you get them?
“I mainly use chestnut shells sourced from processors in Asturias, Galicia, and El Bierzo, collected near my studio. I use biological binders like gelatin, agar agar, and starch. Everything is local and organic, which minimizes environmental impact and strengthens our circular economy philosophy.”
5. What techniques and tools do you use?
“My work combines digital techniques—3D modeling and additive manufacturing to create molds—with manual processes such as modeling, natural drying, sanding, and finishing with natural oils or shellac. I also occasionally use laser cutting. This hybridization of technology and craftsmanship produces unique biomimetic forms.”
6. Is your craft innovative or endangered?
“It’s clearly in a phase of revaluation. While traditional craftsmanship is at risk, innovation with biomaterials offers a sustainable and culturally powerful path. I believe professions like mine, which integrate technology, nature, and creativity, are the future of artisanal design and should be recognized as high-impact career options.”
7. How did you train?
“I started with Graphic Design at ESAPA (2007), continued with a master’s in Multimedia Design at ELISAVA (2009), and led art and animation projects between 2010–2018. Since 2018, I launched Volumínica, a design and interior studio; from 2020, I’ve been running Laboratorio Biomimético, a research and training center in biomimicry; and as of 2024, I’ve started the ARBIO brand, under which I create functional or artistic pieces.”
